Toggle buttons and the switch widget both suffer usability problems for me. The visual look of a button represents an action to be performed in my mind, perhaps why it was referred to it as a soft-action? So when a button is stateful it can create ambiguity depending on the text of the button. The old, "Does it perform the action shown on the label or does the label reflect the current state?" This causes dissonance in my mind which can hopefully be resolved by the widget having another visual indication of the state (the depressed look). A typical example of this failure is with Glades usage of toggle buttons on a selected widgets properties (don't mean to offend anyone here, just stating my experience!). This is further confused by the text changing when you press the button to Yes or No.
Moving on to the switch widget, I think it mostly suffers the same issues I've described. Does the text on the switch widget represent the current state or the action of setting the state to on or off. Again the visual indication barely saves me here (having it highlighted to blue). Given this, the visual indication aside from the text is what I use to determine the state of either a toggle or switch. This makes me think the text on the widget only confuses things and the widget could simply be a checkbox which would resolve all visual ambiguity. However, I do see value in what is described in the UX guidelines regarding the switch widget and associating it with things that take time (not just a simple checkbox state). The guidelines also don't describe explicit styling of the switch which is my problem with it. I think the visual ambiguity could easily be fixed by showing both available states, looks like it is already being discussed here: https://bugzilla.gnome.org/show_bug.cgi?id=644658 -Simon On Sat, Aug 4, 2012 at 8:47 AM, David Nečas <y...@physics.muni.cz> wrote: > On Sat, Aug 04, 2012 at 03:39:05PM +0100, Emmanuele Bassi wrote: > > one implies a "soft" action (GtkToggleButton), whereas the other > > implies something similar of a hardware switch (GtkSwitch). > > As every user knows, widgets relay wishes to magic pixies.
